That's typical for an Auburn. Just add a bottle of Ford or GM limited slip oil additive to it and drive it a while. It should be all right. Don't do anything else to it and don't use any other type of oil additive. I've always had to use 2 bottles of additive for the Auburn.

Thanks.
I'll give that a try. It's cheap and easy to do so if it works, I'll be happy.

I did call Auburn Gear just for interest. Got transferred to a tech and then got voicemail. I left a message but it's been an hour and a half now and no call back yet.

I did a google search on this but most people complain of a grinding noise or chatter but mine is more of a mild squawk.
